Inventor Patented Mar. 13, 1945 ADJUSTABLE PICKING MOTION Peter EmilleProvost, Pawtucket, B. 1. Application Februarym, 1942, Serial No.430,984

4 Claims. (01. 139-150) The present invention relates to new and use-.ful improvements in pick motions and in par-- ticular to picking motionson automatic filling changing Draper looms, and comprises an improvementon my prior Patent No. 2,229,899, dated January 28, 1941.

An object of the present invention is to provide simple and practicalmeans for adjusting the pickershoe on the picker stick, and which at thesame time is efficient and reliable in performance, relativelyinexpensive to manufacture and otherwise well adapted for the purposesfor which the same is intended.

Other objects and advantages reside in the details of construction andoperation as more fully hereinafter described and claimed, refer encebeing had to the accompanying drawings forming part hereof, wherein likenumerals refer to like parts throughout, and in which:

Figure 1 is a sectional view through the picker stick with the shoeshown" in plan.

Figure 2 is a side elevational view thereof.

Figure 3 is a sectional view taken substantially on a line 3-3 of Figurel, and

Figure 4 is a sectional view taken substantially v is inserted and heldin position by the head l2 of the bolt.

The shank i is of channel shape in crosssection and has its upper endoffset from the picker stick, as shown at l3, and threaded through theoffset upper end I3 is an adjusting screw I4 adapted to bear against thetongue l5 positioned in the channel of the shank, the

tongue also being of channel shape in cross-section and in which thepicker stick is positioned. The set screw I4 is secured in lockedposition by a jam nut I6. The tongue I5 is also formed with a verticalslot IT to freely accommodate the bolt 6.

Positioned between the tongue l5 and the picker stick- 5 is a plate l8having prongs l9 adapted for embedding in the picker stick, the platealso having an opening 2!] to receive the bolt 6.

The upper end of the tongue I5 is formed with a shoulder 2i underlying ashoulder formed on the upperend of the plate l8 and through which a setscrew 23 is threaded, the lower end of the screw being adapted to bearupon the shoulder 2|, as shown to advantage in Figures 2 and 3 of thedrawings. Theset screw 23 is secured in adjusted position by a jam nut24.

From the foregoing it will be apparent that the shoe 9 may be adjustedvertically on the picker stick by loosening the bolt 6 and loosening theset screws l4 and 23, and the tongue I5 may likewise Having thusdescribed the invention what I claim is:

1. In a device of the class described, a picker stick, a shoe adjustablypositioned on the stick, said shoe including a shank having a vertical.slot therein, a bolt fixed to the stickand positioned in said slot forvertically adjusting the shoe on the'stick, a tongue positioned betweenthe shank and the stick, and including a part resting on the shank andmeans including vertical and horizontal set screws bearing respectivelyagainst the top and side of the tongue and adapted for securing the samein vertically ad justed position relative to the stick.

2. In a device of the class described, a picker stick, a shoe adjustablypositioned on the stick, said shoe including a shank having a verticalslot therein, a bolt vertically fixed relative to the stick andpositioned in said slot for vertically adjusting the shoe on the stick,a tongue positioned between the shank and the stick, a shoulder on theupper end of the tongue overlying and resting on the shank, a vertica1set screw carried by a part fixed relative to the picker stick andbearingagainst the shoulder of the tongue, and a horizontal set screwcarried by the shank and bearing against the tongue.

3. In a device of the class described,fa picker stick, a shoe adjustablypositioned, on the stick, said shoe including a shank having a verticalslot therein, a bolt carried by the stick and positioned in' said slotfor vertically adjusting the shoe on the stick, a tongue looselypositioned on the bolt at one side of the shank, a plate positionedbetween the tongue and the picker stick and secured against movementrelative to the latter, a shoulder on the upper end of the tongueresting on the shank, a shoulder on the upper end of the plate overlyingthe first-named shoulder, a set screw carried by the second shoulderengaging the first shoulder for vertically adjusting the tongue relativeto the stick, and a set screw carried by the shank and engaging thetongue to secure the same against relative vertical movement.

4. In a device of the class described, a picker stick, a shoe adjustablypositioned on the stick, said shoe including an upstanding channeledshank having a vertical slot, a tongue of channel shape in cross-sectionpositioned in the shank, said tongue receiving the stick and said tonguealso having a vertical slot aligned with the slot of the shank, a plateinterposed between the tongue and the stick and anchored to the latter,a bolt carried by the stick and inserted through said slots, and meansoperating in vertical and horizontal directions against the tongue foradjustably securing the shank and tongue longitudinally of the stick.
